Rolled Ball Screw Processing
ALM rolled ball screw threads are created by pushing each uncut bar blank into a rotary tool die in a single operation.Rolling is the common process for ball screws,and it is more economical and sufficiently accurate for most industrial applications.
Rolled Ball Screw Thread
The picture on the left shows the details of the ALM rolled ball screw threads,which are clean and smooth and have excellent surface finish.Miniature rolled ball screws are available with very fine leads.This is a significant advantage in applications requiring fine-adjustments and micro-positioning.
